Product Details

TotalBoat Penetrating Epoxy is a low-viscosity wood rot restoration and repair solution that seals deeper & cures stronger than industry-leading penetrating epoxies. It has no VOCs, no odor & is 100% waterproof once cured.

This 2:1 system is ideal for restoring rotten or damaged wood, or sealing new wood for lasting protection against humidity, salt, mold & mildew. It works by gluing cellulose (wood) fibers back together, sealing a bare, porous wood surface from the inside out. Double the penetrating power by mixing acetone with the epoxy resin solution in equal volume. Easy to apply by brush, roller, or inject via syringe. Surfaces may be painted or varnished after light sanding.

Choose from Traditional (65-90 F) or Cold Weather (40-65 F) formulas in Pint, Quart, 1/2 Gallon & Gallon kits.

Info & Guides

NO VOCS, NO SMELL.

Cleanup is easy. Wear latex gloves, wash off with soap and water. No solvents required.


APPLICATION NOTE: The wood must be bare and unfinished. Also, TotalBoat Penetrating Epoxy will not penetrate and level well when applied over some stains. Always test an area first. DO NOT USE on top of Minwax oil-based stains.


TotalBoat Cold Weather Penetrating Epoxy is perfect for use during the colder seasons. Compared to our traditional TotalBoat Penetrating Epoxy, our Cold Weather formula offers similar performance characteristics, but cures completely and reliably in cooler temperatures. Its tack-free properties also allow you to sand sooner.

WARNING: TotalBoat Cold Weather Penetrating Epoxy should not be used as a fast-cure epoxy in warmer temperature conditions because doing so can be unsafe and result in premature exotherm, brittleness, and improper curing.

Application Temperature Ranges:

  • Traditional formula - 65-90°F
  • Cold Weather formula - 40-65°F

The jury isn't in yet
By Phil the drill from Catskill from Blacklick, Ohio

Verified Purchase

Just getting started on my two wooden rowboats. Been in storage all winter. Noticed some rotting halfway down the port side gun wall on one of the boats.

Perfect for window and door sill restoration
By Tekton Proulx LLC from Middle Haddam, CT

Verified Purchase

Both the cool weather and warm weather products were used with excellent results. With a few well placed holes drilled the epoxy penetrated deep into the wood fibers. I also had an opportunity to cut a cross section and was amazed how well the epoxy penetrated.

Bottom Line Yes, I would recommend to a friend

Works well if mixed properly
By Matt from WI

Verified Purchase

It's good stuff, but it must be exactly mixed or else you'll muck up your project. I prefer West System 655, which is a 1:1 ratio, and sets less than 24 hours, cures in about 2 days.

Bottom Line No, I would not recommend to a friend

Works great
By JustGood from Long Island, NY

Verified Purchase

I got this kit to stabilize an Amboyna Burl guitar top. The top was beautiful and I wanted to keep as much of it intact for the finished piece. Just so happens that part of it was very soft, and if left untreated would have easily broken off. After painting on with a disposable brush, I allowed it to remain untouched for 3 days (overkill, I know). It came out perfectly. I was able to get the result I was looking for and am very happy. I don't believe I'll need to use it very often, but if and when this supply runs out, I will definitely purchase again.

Bottom Line Yes, I would recommend to a friend

A (maybe) unintended use that worked out well
By Old Grumpy Kayaker from Edwardsburg, MI

Verified Purchase

I just completed a Greenland style kayak paddle out of Northern White Cedar. The only cedar that I could find that was knot-free was very porous, soft and prone to dents. After the final sanding I coated it with one coat of Total Boat Penetrating Epoxy thinned 75% with acetone, recoating the dry spots as necessary followed by a second coat thinned 30%, again recoating as necessary to level any low spots. Final coat full strength on tips & end grain. Wood now thoroughly sealed and much more durable. Allowed 72 hours before final sanding & 3 coats of water-based varnish. The penetrating epoxy significantly hardened the wood and made an excellent base / prep coat. In retrospect had this product been available when I built my strip-built kayak I would have used it as a prime/bonding coat before laying on the fiberglass.

Bottom Line Yes, I would recommend to a friend
